HARRY E. DONOR, OF NEW YORK, N. Y., ASSIGNOR TO HIMSELF AND ROBERT E. BRETT, '0F SAME PLACE.

IMPROVEMENT IN UMBRELLA-PRAMES.

The Schedule referred to in these Letters Patent and making p'art of the same To all whom it may concern Be it known that I, HARRY E. DONOR, of the city, county, and State of New York, have invented a new and useful Improvement in Umbrella-Frames; and I.

do hereby declare that the following is a full, clear,

and exact description of the same, reference being had to the accompanying drawing forming a part ot' this specification.

Referring to the accompanying drawing- Figure l represents a plan view of au umbrella-frame to which my invention is applied;

Figure 2, a vertical section of the same Figure 3 represents the xed and sliding collars def tac-hed from the frame; and V Figure 4 represents a transverse section of one of the ribs, tak-en through the point of connection of the stretcher therewith, illustrating the manner of attaching the block to rib and of connecting the stretcher to the block.

Similar letters of reference indicate corresponding parts in the several figures.

, A is the stick of an ordinary umbrella-trame.

B B'are the notch or lixed collar and the runner or sliding collar, the one secured upon the stick near the upper extremity thereof, and the other made to slide upon the central portion thereof.

Said collars B B' are provided with heads b b', having openings aa', corresponding in number to the ribs and stretchers, and designed for the reception of the same.

Hitherto, so far as I am aware, no means have been, rprovided whereby the ribs and stretchers might be de# ever, very desirable that both the ribs and stretchers should be individually detachable, each from the other and from their respective notches, Ifor the purpose of repair, and that in such a manner as to allow the detachment tobe effected almost instantaneously. To

this end, Ibend the/ends of the stretchers G to form a right angle, and also the inner ends of the ribs O in the same manner. When thus bent, it will be perceived that the same may be readily connected together by means of the laps ll, and also to the runner and notch, as required, with a simple movement involving a small frac-tion'of time. Their detachment may, of course, be eected with equal facility.

This construction of ribs and stretchers enables them to be furnished at less cost than any heretofore known, as but a single wire is requisite, and after being cut Ainto suitable lengths, nothing more is required save f p to form the angularterminations at their ends. If. pref fel-red, the latter may be made slightly hook-shaped, to insure a more secure connection of parts I am aware that angular projections or enlargements ou the ends of' the ribs and stretchers of umbrellas have been previously employed, but such involving greater pose specilied.
